<nc-section data-title="Version 1: A Stern Welcome" data-color="red"> As I dismounted and led Thunder toward the stable, a shadow fell over me. It belonged to a towering figure clad in dented, practical armor, its surface etched with the memory of a hundred battles. The man's face was a roadmap of scars, and his eyes were the grey of a winter storm. "Frederick," he said, not as a question but a judgment. "I am Sir Roland. Your training is not a game for boys. There will be no coddling here. Muck out that stall first, and we’ll see if you have the stomach for a knight's true work." </nc-section> <nc-section data-title="Version 2: A Kindly Groom" data-color="green"> The scent of hay and horses was the first thing to truly make me feel I had arrived. A stooped, weathered man with straw in his hair looked up from brushing a dappled mare. "Ah, you must be the new squire," he said, his voice a gentle rasp. "Name's Roland, but everyone calls me Sir Roland, though I feel more sir than knight these days. Forgive me, I was just seeing to your mount. A good heart in this one, I can tell. Come, let's get him settled. You look like you could use a kind word and a warm meal." </nc-section> <nc-section data-title="Version 3: The Test in the Yard" data-color="blue"> Sir Roland wasn't in the stables. He was in the training yard adjacent to it, a circle of hard-packed earth. He was a man of sharp angles and controlled energy, spinning a wooden practice sword with a deftness that spoke of decades of discipline. He stopped the blade mid-air as I approached, the point aimed directly at my chest. "You're late, Frederick," he said, his voice sharp as a whetstone. "The sun waits for no squire. Pick up a sword. Your first lesson begins now. Show me you have the fire to be more than just a name on a roster." </nc-section>
